Benefits of technology

[0028]The backrest of the chair extends between a proximal end and a second distal end, said proximal end being adjacent to the seat such that the width of the chair reduces between said proximal end and said distal end. This reduces any obstruction of the movement of the arms of a person whose chest is resting on the backrest, when the chair is in the support configuration.

Problems solved by technology

A downside of this is that farmers have to carry out certain weeding, maintenance or harvesting tasks manually.
This makes the work laborious, without mentioning the possible consequences for health: backache, joint pain, etc.

Embodiment Construction

[0043]FIG. 1A shows an example of a chair 1 according to the invention, arranged on an agricultural device 2 designed for market-gardening tasks. The agricultural device comprises a chassis 3 supported by four wheels 4. These wheels define, in pairs, a front axle and a rear axle. The device may be controlled by a person seated on the chair 1, the chair being in a first configuration referred to as the seating configuration. The chair comprises a seat 10 on which a person can sit, and a backrest providing dorsal support. The device comprises a platform 6, which is arranged at the front and on which it is possible to place tools or trays 7. The device may support tools 37 arranged at the front and / or at the rear.

[0044]In all of the figures that illustrate the invention, reference is made to an XYZ coordinate system in which the X and Y axes define a horizontal plane that is parallel to the surface of the ground and on which the device rests, while the Z axis defines a vertical plane t...

Abstract

A chair includes a seat and a back rest, both of which pivot about respective axes between first and second positions thereof about parallel axes of rotation. The seat's second position is inclined relative to a first seat plane defined by the seat's first position. The backrest's second position is essentially parallel to the first seat plane such that the chair switches between seating and support configurations. In the seating configuration, the seat and backrest are their respective first positions such that the chair accommodates a seated person. In the support configuration, the seat and backrest are in their respective second positions such that the chair accommodates a person's chest on the backrest's rear face.

Description

TECHNICAL FIELD[0001]The technical field of the invention is that of chairs, in particular ergonomic chairs, that can be deployed in different configurations. The principal application that is targeted is adaptation to working postures, in particular in the field of agriculture, while other applications may be envisaged, for example in the field of healthcare.PRIOR ART[0002]In spite of increased mechanization, relating to most sectors of industry, certain work is still heavily reliant on human activity. This is particularly true in the field of agriculture, and for example in the field of organic agriculture. It is known that, in a sector such as this, there is a desire to limit or even avoid recourse to techniques that are harmful to the environment, for example the use of pesticides or herbicides. A downside of this is that farmers have to carry out certain weeding, maintenance or harvesting tasks manually. This is particularly true of market gardening, involving multiple manual o...
